Leg numbness

I am a 28y/o male who has had leg numbness for a few months. They go numb(no pins and needles feeling) when I sit or lay wrong. When I stand up, it immediately goes away but I have notice some soreness in my legs and groin, thigh area. I had an MRI on my back to check for a herniated disk and it was normal. My doctor has given my an EKG which was normal, a nerve test(EMG I believe is what it is called) on my legs which was normal, blood work was normal, I have had a doppler on both legs and both was normal. I was wondering if anyone had any ideas? Could it be a pinched nerve or what?
